Calculate the volume of hydrogen that can be obtained by reacting 450 g of 9.8% sulfuric acid with an excess of aluminum

Metallic aluminum interacts with sulfuric acid. In this case, aluminum sulfate is synthesized and bubbles of hydrogen gas are released. The reaction is described by the following equation.

2Al + 3H2SO4 = Al2 (SO4) 3 + 3 H2;

Let’s calculate the chemical amount of sulfuric acid. To do this, divide its weight by the weight of 1 mole of the substance.

M H2SO4 = 2 + 32 + 16 x 4 = 98 grams / mol;

N H2SO4 = 450 x 0.098 / 98 = 0.45 mol;

The sulfuric acid will react to produce the same amount of hydrogen gas.

Let’s calculate its volume.

To this end, we multiply the chemical amount of the substance by the volume of 1 mole of gas (filling a space with a volume of 22.4 liters).

V H2 = 0.45 x 22.4 = 10.08 liters;
